Nissan Almera Classic - one of the most popular sedans in Russia, known for its reliability and unpretentiousness. However, even such a time-tested car has weak points, one of which is the cooling system. Wrong choice or late replacement antifreeze can lead to engine overheating, radiator corrosion, or even pump failure. In this article, we will look at what antifreeze is filled in from the factory, what analogues are suitable, how to replace it correctly and what to look for when purchasing.
Many owners Almera Classic (especially models N16 And B10) are faced with confusion: the manual lists some specifications, dealers recommend others, and on the forums others advise others. We analyzed official data Nissan, reviews from car owners and technical characteristics of fluids to give an accurate answer. You will also find out why It is strictly forbidden to mix antifreezes of different colors in Almera Classic - this is one of the main reasons for breakdowns of the cooling system in this car.
Original Nissan antifreeze for Almera Classic: part numbers and specifications
From factory to Nissan Almera Classic (including restyled versions) antifreeze is poured from the manufacturer itself. Official name - Nissan Long Life Coolant (blue or green, depending on the year of manufacture). This liquid meets strict standards Nissan and has an extended life formula designed to 5 years or 100,000 km.
Main articles of original antifreeze:
- 🔹 KE902-99932 — concentrate (1 l), requires dilution with distilled water in a ratio of 50/50.
- 🔹 KE902-99931 — ready-made liquid (1 l), already diluted for temperatures down to -37°C.
- 🔹 KE902-99944 — concentrate (5 l), for complete replacement.
Important: original antifreeze Nissan produced by the company Calsonic Kansei (conveyor supplier) and has a unique additive package that prevents corrosion of aluminum engine parts QG15DE And QG18DE, which comes with Almera Classic. The use of non-original fluids without appropriate approvals can lead to the formation of sediment in the radiator.

Tolerances and standards: which antifreeze is suitable for Almera Classic
If the original antifreeze Nissan is unavailable or too expensive, you can use analogues that meet the following standards:
| Standard/approval | Description | Examples of compatible brands |
|---|---|---|
| Nissan Coolant L248/L250 | Official approval for antifreeze Nissan ethylene glycol based | AWM Coolstream Premium, Ravenol HJC |
| JIS K 2234 | Japanese standard, similar G11, but with improved anti-corrosion properties | Eneos Super Coolant, Mitsubishi Super Long Life |

| ASTM D3306 | American Standard for Ethylene Glycol Antifreeze | Valvoline Zerex G05, Peak Global Lifetime |
Pay special attention to antifreeze color. B Almera Classic filled from the factory blue or green antifreeze (depending on year of manufacture). Red or purple antifreeze (G12+, G13) is absolutely not suitable - it contains other additives that may react with the original liquid and cause the formation of a gel.
⚠️ Attention: If you purchased used Almera Classic and you don’t know what kind of antifreeze is filled, be sure to flush the cooling system before replacing. Mixing incompatible fluids is the main cause of thermostat and pump failure in these cars.
Antifreeze volume in the Almera Classic cooling system
Total cooling system volume Nissan Almera Classic depends on engine type and configuration:
- 🔧 Engine
QG15DE(1.5 l) — 6.7 liters (including heater radiator). - 🔧 Engine
QG18DE(1.8 l) — 7.2 liters.
When completely replacing antifreeze, it is recommended to purchase 8 liters finished liquid or 4 liters of concentrate (for dilution in a ratio of 1:1). Please note that when draining old antifreeze, about 1–1.5 liters liquid, so additional volume may be required for flushing.
If you are planning a partial replacement (topping up), use only the same brand and color of antifreeze that is already filled. To check the level, use the expansion tank - it should be between the marks MIN And MAX on a cold engine.
Before replacing antifreeze, drain the old fluid on a cold engine - this will reduce the risk of burns and damage to the pipes. To speed up the process, open the heater tap to maximum.
Step-by-step instructions for replacing antifreeze in Almera Classic
Replacing antifreeze in Nissan Almera Classic does not require special skills, but it is important to follow the sequence of actions. You will need:
- 🔧 New antifreeze (8 l or 4 l of concentrate + 4 l of distilled water).
- 🔧 Container for draining old liquid (at least 10 l).
- 🔧 Key for 10 or 12 (for the radiator drain plug).
- 🔧 Screwdriver (for removing pipe clamps).
- 🔧 Distilled water (for rinsing, if required).

Step 1. Drain the old antifreeze
1. Place the vehicle on a flat surface or overpass.
2. Open the cap of the expansion tank (this will relieve pressure in the system).
3. Place a container under the radiator drain plug (located in the lower left corner).
4. Carefully unscrew the plug with a 10 or 12 wrench and wait until the liquid is completely drained.
5. To drain completely, disconnect the lower radiator pipe (an additional ~0.5 liters of antifreeze will leak out).
Step 2: Flush the system (if necessary)
If the old antifreeze is cloudy, with sediment or rust particles, the system needs to be flushed:
1. Fill the radiator with distilled water (5–6 l).
2. Start the engine and let it idle for 10–15 minutes.
3. Drain the water and repeat the procedure 2-3 times until the drained liquid is clear.
Step 3. Filling with new antifreeze
1. Reinstall the drain plug and pipes.
2. Fill new antifreeze into the expansion tank to the mark MAX.
3. Start the engine and let it run for 5-7 minutes with the reservoir cap open (this will help expel the air).
4. Add antifreeze to the level and close the lid.
⚠️ Attention: After replacing the antifreeze, check its level for the first 2-3 days - there may be air pockets in the system that will come out over time. If the level drops, add fluid to the correct level.
Using undiluted antifreeze concentrate will cause the fluid to freeze at -10°C and increase the risk of corrosion. Always dilute the concentrate with distilled water in a 1:1 ratio (for temperatures down to -37°C).
Common mistakes when replacing antifreeze and their consequences
Even experienced car owners sometimes make mistakes that can lead to serious damage. Here are the most common:
- 🚫 Mixing antifreeze of different colors or brands - leads to the formation of sediment, which clogs the radiator and pipes. B Almera Classic this often causes the engine to overheat.
- 🚫 Using tap water instead of distilled water — the salts and minerals it contains accelerate the corrosion of aluminum parts.
- 🚫 Incomplete drainage of old antifreeze — the remaining fluid is mixed with the new one, shortening the service life of the additives.
- 🚫 Replacing antifreeze on a hot engine — risk of burns and deformation of plastic elements of the system.
- 🚫 Ignoring air jams - may lead to incorrect operation of the heater or overheating.
One of the most dangerous mistakes is use of antifreeze with silicate additives (For example, G11 European standard). In engines Almera Classic With an aluminum cylinder block, such additives form an abrasive residue, which over time destroys the pump and thermostat seals. Official service manuals Nissan directly prohibit the use of silicate antifreeze in these models.
What happens if you fill in the wrong antifreeze?
Incompatible additives can react to form a gel-like mass that can clog the radiator and heater passages. As a result, the engine will begin to overheat and the heater will stop working. In severe cases, this leads to deformation of the cylinder head and major repairs.

When to change antifreeze in Almera Classic: signs and frequency
Official regulations Nissan requires replacement of antifreeze every 5 years or 100,000 km (whichever comes first). However, in Russian conditions (sharp temperature changes, poor quality of roads), it is better to reduce this interval to 3–4 years or 60,000–80,000 km.
Signs that it’s time to change the antifreeze:
- 🔴 The color has changed (darkened, became cloudy or rusty).
- 🔴 Sediment or flakes are visible in the expansion tank.
- 🔴 The cooling fan often works (a sign of overheating).
- 🔴 The stove blows cold air (there may be an airlock or clogged channels).
- 🔴 Antifreeze foams or has oily stains (a sign of mixing with oil).
To check the condition of antifreeze you can use test strips (sold in auto stores). They show the pH level and additive content. If the pH is below 7.5 or above 10.5, the antifreeze has lost its properties and requires replacement.
⚠️ Attention: If oily streaks appear in the antifreeze, this is a sign of damage to the cylinder head gasket. In this case, replacing the fluid will not help - engine diagnostics are required.
